Can cPanel migrate from VPS/Plesk?

Hi guys.
I'm running a VPS with Plesk 7.5.4 migrated fine from cPanel 9 reseller account by Plesk Migration Manager. But now I'm tired of Plesk hermetic problems and I want to return to cPanel (VPS). I contacted a web hosting company using cPanel for its VPS and the Admin said: "We cannot perform migrations from a Plesk system to a cPanel system, unfortunately, as they are incompatible platforms." This is true?!!

Yes, and No.
Yes, it is incompatible, in the sense that cPanel Migration System only support Plesk 6.x and down.
No, in the sense that it does support Plesk, and will migrate some of the stuff over. You'll want to do a search to find out what steps would need to be taken, such as mailbox resets, subdomain recreation, mailing list migration, and such.
cPanel is currently updating their Migration system to support the latest Plesk builds, but they're not exactly racing through it.http://bugzilla.cpanel.net/show_bug.cgi?id=2788 is tracking the progress.
